Albuterol

Brand Name - Ventolin

General Information

Albuterol is similar to other bronchodilator drugs, such as Metaproterenol and Isoetharine, but it has a weaker effect on nerve receptors in the heart and blood vessels; therefore, it is somewhat safer for people with heart conditions.

Albuterol tablets and syrup begin to work within 30 minutes and continue working for up to 8 hours. There is also a long-acting tablet preparation JRepetabs) that continues to work for up to 12 hours. Albuterol inhalation begins working within 5 minutes and continues for 3 to 8 hours.

Cautions and Warnings

Albuterol should be used with caution by people with a history of angina (chest tightness/pain), heart disease, high blood pressure, stroke or seizure, diabetes, thyroid disease, prostate disease, or glaucoma. Excessive use of Albuterol inhalants can lead to worsening of asthmatic or other respiratory conditions, and can lead to increased breathing difficulty, instead of providing breathing relief. In the most extreme cases, people have had heart attacks after using excessive amounts of inhalant.

Animal studies with Albuterol have revealed a significant increase in certain kinds of tumors.

Possible Side Effects

Albuterol’s side effects are similar to those of other bronchodilators, except that its effects on the heart and blood vessels are not as pronounced.

• Albuterol’s effects may be increased by monoamine oxidase (MAO) inhibitor drugs, tricyclic antidepressants, thyroid drugs, other bronchodilator drugs, and some antihistamines.• The chance of cardiotoxicity may be increased in people taking Albuterol and Theophylline. Albuterol is antagonized by beta-blocking drugs (Propranolol and others). Albuterol may antagonize the effects of blood-pressure-lowering drugs, especially Reserpine, Methyldopa, and Guanethidine.• Albuterol may reduce the amount of Digoxin in the blood of people taking both drugs. This could result in the need to adjust the Digoxin dose.

Food Interactions

Albuterol tablets are more effective when taken on an empty stomach; or 1 hour before or 2 hours after meals, but can be taken with food if they, upset your stomach. Do not inhale Albuterol if you have food or anything else in your mouth.

Overdosage

Overdose of Albuterol inhalation usually results in exaggerated side effects, including heart pains and high blood pressure, although the pressure may drop to a low level after a short period of elevation. People who inhale too much Albuterol should see a doctor, who may prescribe a beta- blocking drug (such as Metoprolol or Atenolol) to counteract the overdose effect.

Overdose of Albuterol tablets is more likely to lead to side effects: changes in heart rate, palpitations, unusual heart rhythms, heart pains, high blood pressure, fever, chills, cold sweats, nausea, vomiting, and dilation of the pupils. Convulsions, sleeplessness, anxiety, and tremors may also develop, and the victim may collapse.

If the overdose was taken within the past half hour, give the victim Syrup of Ipecac to induce vomiting. DO NOT GIVE SYRUP OF IPECAC IF THE VICTIM IS UNCONSCIOUS OR CONVULSING. If symptoms have begun to develop, the victim may need to be taken to a hospital emergency room (call for instructions). ALWAYS bring the prescription bottle.

If you are inhaling Albuterol, be sure to follow the inhalation instructions that come with the product. The drug should be inhaled during the second half of your breath, allowing it to reach deeper into your lungs. Wait about 5 minutes between puffs, if you use more than 1 puff per dose.

Do not take more Albuterol than prescribed by your doctor. Taking more than you need could actually worsen your symptoms. If your condition worsens rather than improves after taking your dose, stop taking it and call your doctor at once.
